The present invention refers to a device for guiding, in a room to beventilated, an air stream blown through a ventilation outlet.

In air distributors of prior and actual manufacture aiming at the sameobject the direction of the air flow is controlled by directing aportion of pipe fastened either inside-a sphere revolving as a swivelassembly or to an intricate system allowing an omnidirectional positionof the device.

In the device according to the invention the direction of the air flowis obtained by fins movable in all directions and located inside theventilation opening itself.

These fins consist preferably of half circular plates assembled along asame diameter-for instance four half circular plates assembledsubstantially at right angles-which can be moved in all directionsinside a circular aperture of substantially the same diameter as thesaid plates and forming the ventilation outlet proper.

The articulation of the fins in the above mentioned circular aperturemay be obtained by forming the edges of this opening either by two fiatrings of a slightly smaller diameter than the fins and located inparallel planes, one in front and the other at the back of the center ofthe set of fins, or in the shape of a spherical ring of substantiallythe same diameter as the fins, said fins being frictionally clasped bytheir periphery in these rings. According to another embodiment of theinvention, each fin may be provided in its center with a half circularhole, said holes being of the same diameter for all the fins andenclosing a same central spherical core fastened by radial members tothe edges of the ventilation outlet.

According to an additional characteristic of the invention, the edges ofthe aperture figuring the outlet are advantageously, at least partiallyresilient so as to provide a tight fitting in cooperation with the fins.

The annexed drawings show two embodiments of a device according to theinvention. In these drawings:

Figure l is a somewhat diagrammatic perspective view of a first type ofsuch a device,

Figures 2 and 3 are two horizontal diametrical cross-sections of apractical embodiment of said device, for two different positions of thefins,

Figure 4is a diagrammatical front view of another type ofdeviceaccording to the invention,

' Figure 5 is a diametrical cross-section of a practicalembodiment ofthe device according to Fig. 4, taken on the'line 5-5 of Figure 6,.

Figure 8 is a diagrammatical view of the central articulation of thefins, j

- Figures 9, lflai'id'l'l'ar diagrams showing varilet as shown in Figs.2 and 9. When said axis manner, the opening of an air duct not shown inthis figure, the edges 4 of the opening 2 being shaped as a sphericalring.

In the device shown in Figures .2 and 3, the.

opening 2, of a slightly smaller diameter than the fins l is provided ina plate 5 simultaneously used to secure the device on the wall (notshown) of'the room to be ventilated or on a collar 6 formed at the endof the air duct 1. On this plate 5 is fastened a ring 8 thecross-section of which is approximately 2 shaped, said ring leaving acentral opening 9 of a slightly smaller diameter than that of the finsI, the openings 2 and 9 enclosing said fins. A rubber ring I0 is locatedinside ring 8.

According to Figure 4, the center of each of the fins I is provided witha half circular recess ll concentric to said fins. The edges of theserecesses enclose a spherical core [2 the center of which is incoincidence with the center of opening 2, the core 12 being fastened inthe opening 2 by radial arms l3.

In the construction shown in Figs. 5 and 6 of the type of deviceaccording to Fig. 4, the arms 13 of the spherical core l2 are fastenedby screws M to the plate 5, said plate being fastened by screws l5,either to the wall of the room to be ventilated, or at the end of theair duct. The screws I4 are also used to secure two metallic rings I6forming opening 2, a ring shaped rubber gasket l1 being clasped betweensaid rings.

The spherical core may be either constructed as a one piece unit and,preferably, in a resilient material that can be compressed by the fins,or made of two stiff caps I8 (Fig. 8) one of them linked to both of thearms IS, the other being free of fastening, a spring l9 keeping thesetwo caps apart from one another.

In the latter type of construction, the whole set of fins l consists ofat least two parts assembled by any known means, as for instance, bysoldering, by rivets or byscrews, but not fastened to the spherical corewhich serves only as a central bearing for the fins.

In both the arrangements shown in Figs. 1 or 4, it is possible to giveany desired direction to the fins, so asto direct, to control and evento stop the flow of air used for ventilation. If a central swivel isused for controlling purposes the said swivel focusses the air flow onthe fins.

figured by the'intersection of the four fins when said axis crosses'theplane of the ventilation outlet 2, the ventilation outlet is obstructed,as "shown properties either of the edges of the opening 2',' 'or ofthesphericalcore l2. The resilient'gasket pro: v'i'ded-on the edges,which may consist either di 1;; rubber gasket or of one or more metallicextensible gaskets, insures further the tightnes'sof the device if theopening 2 is shut, as shown in Figs.
